Ibuki Niijima, a proactive and athletic leader of the DJ unit Photon Maiden and student council president at Yoba Academy, channels her lifelong passion for movement into performance. Growing up immersed in sports, she pivoted to dance and vocals during junior high after training at a show production school, a shift that now fuels her mentorship. She prioritizes her group’s artistic and physical growth, blending a nurturing "big sister" approach with vibrant guidance to foster her teammates’ self-expression—exemplified by her support for Saki Izumo’s creative exploration.

Confident yet unassuming, she deflects praise for her popularity among underclassmen, even as peers like Hiiro and Kyoko acknowledge her influence. Grey hair tied in a sleek ponytail and blue-grey eyes frame her 165 cm stature. Descended from shrine caretakers, she occasionally serves as a miko at her family’s shrine. Though blessed with a rapid metabolism allowing hearty meals, she moderates her diet to match her active lifestyle.

Beyond music and student governance, she coaches Yoba Academy’s track team and engages in cross-media projects featuring designs inspired by figures like Deviljho and Nakano Itsuki. Her name echoes her persona: "Niijima" (new island) and "Ibuki" (clothes/dance/record or breath/vigor) mirror her dynamic blend of reinvention, artistry, and vitality within Photon Maiden’s narrative.
